AAQ-2: Utility Area The sampler was placed near Utility area in the factory. Ambient Air Quality Monitoring Methodology Monitoring was conducted in respect of the following parameters: Particulate Matter 2.5 (PM 2.5) Particulate Matter 10 (PM 10) Sulphur Dioxide (SO 2 ) Oxides of Nitrogen (NO x ) The duration of sampling of PM2.5, PM10, SO 2 and NOx was 8 hourly continuous sampling per day and CO was sampled for 8 hours continuous. The monitoring was conducted for one day at each location. This is to allow a comparison with the National Ambient Air Quality Standards. The air samples were analyzed as per standard methods specified by Central Pollution Control Board (CPCB) and IS: Fine Particulate Sampler FPS instruments have been used for monitoring Particulate Matter 2.5 (PM2.5 i.e. <2.5 microns), and Respirable Dust Sampler APM 860 was used for sampling Respirable fraction (<10 microns), gaseous pollutants like SO2, and NOx.

7 AMBIANT NOISE MONITORING Ambiant Noise Monitoring Locations The main objective of noise monitoring in the study area is to assess the present ambient noise levels in factory site due to various operational allied activities and increased vehicular movement and machine. A preliminary reconnaissance survey has been undertaken to identify the major noise generating sources in the area. Ambient noise monitoring was conducted at one location at the main gate of the factory, as given in Table Details of Ambient Noise Monitoring Stations S. No. Location Location Name/ Description Present Land use Code 1 N1 Near Factory Main Gate Industrial Unit Methodology of Noise Monitoring Noise levels were measured using integrated sound level meter manufactured by Quest Technologies. The integrating sound level meter is an integrating/ logging type with Octave filter attachment with frequency range of 31.5 to Hz. This instrument is capable of measuring the Sound Pressure Level (SPL), Leq and octave band frequency analysis. Noise level monitoring was carried out continuously for 24-hours with one hour interval starting at 6.00 am hrs to 6.00 am hrs next day. The noise levels were monitored on working day only. During each hour Leq were directly computed by the instrument based on the sound pressure levels. Lday (Ld), Lnight (Ln) and Ldn values were computed using corresponding hourly Leq. Ambient Noise Monitoring Results The location wise ambient noise monitoring results is summarized in Table. 7

Accordingly, a study of assessment of the soil quality has been carried out. To assess impacts of ongoing project activities on the soil in the area, the Physico-chemical characteristics of soils were examined by obtaining soil samples from selected points and analysis of the same. Single sample of soil was collected from the project site for studying soil characteristics, the location of which is listed in Table. Details of Soil Quality Monitoring Location S.

13 The sampling has been done in line with IS: 2720 & Methods of Soil Analysis, Part-1, 2nd edition, 1986 of American Society for Agronomy and Soil Science Society of America. The homogenized samples were analyzed for physical and chemical characteristics (physical, chemical and heavy metal concentrations). The samples have been analyzed as per the established scientific methods for Physico-chemical parameters. The heavy metals have been analyzed by using Atomic Absorption Spectrophotometer and Inductive Coupled Plasma Analyzer.
